Fabrication-error-tolerant, Hybrid Wedge Plasmon Polariton Waveguides for Ultra-deep-subwavelength Mode Confinement at 1550nm Wavelength
Fabrication-error-tolerant Hybrid Wedge Plasmon Polariton Waveguides
2015/5/15
A novel hybrid plasmonic waveguide based on a triangular metal wedge is proposed. The structure could achieve ultra-deep-subwavelength mode confinement with low-loss, while its mode properties are sti...
Symmetry-induced Dispersion and performance penalty in Coupled Resonator Optical Waveguides
Micro-optical devices Coupled resonators
2015/6/8
We show that for fundamental reasons, microdisk based CROWs possess two non-degenerate transmission modes, making their long-planned use in optical communications highly challenging. Interference betw...
